power_mgmt: Add device power management support
Added device power management hook infrastructure. Added
DEVICE_INIT_PM and SYS_INIT_PM macros that creates device
structures with the supplied device_ops structure containing
the hooks.
Added example support in gpio_dw driver. Updated the sample
app and tested using LPS and Device Suspend Only policies.
